Sorbus aria

Sorbus aria - common whitebeam

At first sight, with the undersides of its white-felted leaves flickering in the wind, the common whitebeam doesn’t much resemble the typical mountain ash. Nevertheless it is a member of the large Eurasian genus of mountain ash (Sorbus), though there are many dendrologists who would like to see the whitebeams separated completely as their own genus of Aria. Typical of all 27 whitebeams species is that the leaves are (more or less) entire.
